OAR-WHEEL.

SPECIPIQATION forming part of Letters Patent No. 376,724, dated `)january 17, 1888.

Application tiled October 20, 1887. Serial No. 252,898. (No inodeL)l f- .To all whom it may concern:

Be it known that I, EDGAR PEOKHAM, of

Syracuse, in the county of Onondaga, in the State `of New York, have invented new and useful Improvements in Car-Wheels, of which the following, taken in connection with the accompanying drawings, isa full, clear, land exact description.

This' invention relates to the class of carwheels which have the tire formed separate from the body of thewheel; and theinvention consists in improved means for'1 securing the tire. on the wheel-body, as hereinafter fully described, and specifically set forth in the claims. f f- In the annexed drawings,Figure 1 is a trans` verse section of my improved tire-lock applied to a car-wheel containing a paper or n-on-metallic core. Fig. 2 is a rear face view of said wheelfand Figs. 3 ande. are transverse sections of modifications of my invention.

Similar letters of reference indicate corresponding parts.

A represents the wheel-body, and T the tire. The inner peripheral face of the tire I form at one side with the undercut inward projection e, and the oppositeside of said face of the tire I provide with a circumferential rabbet, a, and with circumferential grooves b and c in the two walls ofl said rabbet. The body of the wheel I provide at one side of `its periphery with a tongue or flange, e, which interlocks with the undercut projection e of the tire.4

When the tire is to be secured to abody containing the nonmetallic core G,as shown in Fig. 1 of the drawings,I prefer to form the llange e on the plate P, whichis securedto the side ofthe body and has its periphery iush with that of the body, and when the body is composed of cast-iron I prefer to clamp an annular wrought-metal plate, p, onthe side ofthe body and form the flange e on said plate, as shown in Fig. 3, ofthe body. On wheelsfor light cars, however, the plate p may be omitted and 5 the flange e' formed directly on the body, as

illustrated in Fig. 4 of the drawings. y

From the opposite side of the periphery of the wheel-body projects a plate, P', which in a paper-covered wheel, as shown in Fig. 1 of the drawings, constitutes one of the side plates of the body, and in aforesaid plate is of the shape of a ring clamped onto the side of the body by bolts or rivetsas represented in passing through the same,

This plate P Figs. 3 and 4 of the drawings. projects into formed at its Outer periphery with al iiange, d, projectingy therefrom in the same direction in which the flange e projects. enters into the groove b. the plate P', I clamp the sectional locking plate or ring I, byA means of bolts or rivets r, passing through the respective plates andintervening body. The plate I projects with/its outer edgepinto the groove c Said flange dv `On the exterior of 6o of the tire, and,

It will be observed that the described cona former from slipping struction and combination of parts allowthe tire to be applied to the wheel and Ato be 'removed when required,while maintaining the body of the wheel intact, by simply removing the locking plate or ring I and tying the plates P P( to the sides of the usual outer ringyD, of V75- the paper-cored Wheel by `temporarily-introduced bolts.

Having described my invention, what I claim x as new, and desire to secure by Letters Patent, is

and a retaining-plate clamped on the exterior The iianges d and e projecting-` in one and the same direction allow the tirey ofthe aforesaid body-plate and entering with Y its outer edge into the groove-c, substantially as described and shown. A

2. The combination, with the'wheel-body, of plates secured to opposite sides of the body, oneof said plates being ush with the periphery of the body, and the other plate projecting from said body, and both of said plates being provided at their outer peripheries with lateral Ioo anges projecting in one and the same direeets r, clamping the respective plates onto the tion, the tire formed at one side of its inner wheel-body, substantially as described and peripheral face with an undercut inward proshown.
